Coffee stain, tooth decay, or something else?

[KarlA554]

Hello, I am 24M, I don't smoke, and I drink a few times a month.

This is in the top left of my mouth. It doesn’t hurt, I just noticed the discoloration and wasn’t sure what it was. I drink coffee 1-3 days per week so thought it could be from that.

I just saw the dentist two weeks ago and they didn’t mention anything about this, so I’m hopeful they saw it and weren’t concerned rather than missing it if it’s an issue.

Any chance it’s tooth decay or something problematic? And could that white stuff just above the brown spot be tartar, or is that anything to worry about at all?
Thanks!

Could be plaque or calculus with some superficial staining? When last did you have a proper cleaning done?

My last cleaning was on 11/20 and they didn't mention anything about this. They also took X-rays and didn't mention anything about the results to me, so I assumed there were no issues there.
